News impact democracy

The reporting on news in the media can be highly influential on election outcomes and therefore democracy. Bias in coverage of news arises from mainly 2 sources: (1) topics covered as opposed to the ones neglected, (2) the framing of the news which fit into a broader political narrative. A robust scientific analysis of the topic is difficult as the amount of data (articles, headlines, appearances) can be rather large. The paper by Haider et al. (2026) accomplished a major step forward through the systematic treatment of “selection bias” in news coverage. Related to news coverage, selection bias has both a statistical as well as a substantive meaning. The substantive finding of selection bias refers to the fact that the print media studied tend to prefer “horse race stories to policy issues” in upcoming elections, i. e. the focus on opposing candidates rather than the underlying policy choices. The negativity bias in reporting remains another constant in media research.

Human gravity

Long before the establishment of Newton’s theory of gravity, humans have been fascinated by gravity. Elevation from earth, after all, has figured prominently in religious imagery. Mankind’s dream to fly has become so popular that it contributes substantially to ruin the blue planet. Defying gravity as much as feeling the amplified force of it have become a continuous challenge. In sports we adore the bouncing on a trampoline and classical dance derives a lot of its charm from the suspended moments in air. Beware the landing and get accompanied in your first steps.
Modern Dance is equally creative in the challenge to defy human gravity. Trisha Brown (1971) suspended dancers horizontally so that they could walk in space at least along fixed lines and perpendicular to the surface. The physics of our body change in this bird-like position. Dancing in equilibrium on a horizontally suspended line leaves the audience amazed. The spectacular setting and performance at the “Neue Nationalgalerie” transforms the architecture again into a playing ground for choreographers. Suspension from human gravity is hard work, beyond “¾ Walzer” rhythm and, of course, it takes 2 to tango to feel the suspension.

La gaya sienza

Nietzsche published his 1st version of “Die fröhliche Wissenschaft“ in1882. Ever since a controversy over the translation and interpretation of the title broke out. The publication in English referred to the title as “Joyful Wisdom”. A major question remains: is the opus a piece about science in the sense of philosophy, or less rigorous in method and therefore more a kind of general contribution to a perspective on wisdom? 12 x 12 years later of the 1st publication the “Motto” on the opening page should be taken more seriously. “Dem Dichter und Weisen sind alle Dinge befreundet und geweiht, alle Erlebnisse nützlich, alle Tage heilig, alle Menschen göttlich.“ Such a  radical Version of enlightenment as scientific method announced his attempts to demystify everything from religious beliefs to also science as well. The Motto of the 2nd edition in 1887 goes beyond the original one to include himself into this demystification. “Ich wohne in meinem eigenen Haus, Hab Niemanden nie nichts nachgemacht Und – lachte noch jeden Meister aus, Der nicht sich selbst ausgelacht. In a nutshell, mock yourself as much as you mock about anyone else. Can this science be science, intelligence, artificial intelligence or is this already the precursor of „super intelligence“ of the 21st century AI hype?

Gone birding

Birding is fascinating science and hobby. The recent advances in bird song recognition allow to compare the sometimes complex melodies across species. The support by many citizen scientists who collect data on sound, images and environment, made it possible to identify 8 major types of sound snippets. These constitute the basis from which to study or imitate the major bird songs, if you like. The scientific paper by Bacquele et al. (2026) shows that in dense forests the songs are more complex, whereas in open space simple tunes allow to travel far across space. Mating potentials seem to play an interesting role as well. But birding does not stop there. The Brancusi exhibits in the „Neue Nationalgalerie“ in Berlin deal also with the fascination about birds by the artist (image below). We also find depictions of the „bird-man“ in mythology more than 3000 years before our time and ever since. Flying probably brings together our science and dreams about birds and mankind. Science fiction is full of examples of that kind.

Beware Albedo

At times of high radiation from the sun, we suffer from high “albedo” values surrounding us. Albedo is scaled between 0 (black) and 100 (white) and is a measure of the reflection of light. Dark surfaces have a low Albedo, which means they absorb a lot of light and store this energy in form of heating. On the contrary, white surfaces or reflector materials like mirrors absorb very little of light as they reflect the light and, therefore store very little of it as heat.
In housing or urban planning this is an important indicator to take into consideration when planning for summer heat reduction, for example. Inner cities with dense construction, lots of windows, which in most cases absorb rather than reflect sun light, Light absorption and storage during the day will contribute to heat urban environments and inner cities during summer nights. This might be comfortable during winter, but in hot summer days the high reflection value creates additional discomfort.
Greening of cities is a powerful answer as vegetation absorbs the sunlight, but does not store it in form of heat. The glaciers and huge snow fields have shielded us from the earth heating up too fast in the past. Unfortunately, the lack of knowledge about “albedo” has lead us to undervalue these shielding effects. Light absorption by the earth is an additional driver of climate change in form of global warming. (Image: Brussels, Forest, Park Duden Community Gardening 2026-5)

Mammalian Aging

Mammals share a lot of similarities with respect to aging. The researchers Alexander Tyshkovskiy and Vadim N. Gladyshev et al. (2026) spearheaded multiple research to identify similarities across humans, macaques, rodents and mice. The outcome of this overarching study of mammalian aging and mortality is a set of biomarkers that can serve to predict time to death.
Why is this interesting? With the rise of the longevity interest in the 21st century, the need increases to use robust biomarkers that can assess any presumably miraculous innovation to smooth human aging or prolong the time to death. Steps towards “universal transcriptomic signatures” including CDKN1A and LGALS3 (compare across species), which proved to be important in mortality predictions based on the large UK Biodata.
It is the accumulation of damage, which drives  processes of aging . However, “inflammation, replicative senescence, metabolic inhibition and γ-irradiation” can be attenuated or occasionally even reversed. The aging of cellular components has been demonstrated using “modular-specific clocks”.
With these biological advances in the field of biomarkers, the BPS nexus (biology-psychology-society links) could receive more attention as well in order to enlarge the society-wide research into the causes of human aging.

History as Science

There are persons entering history and there is the science of history. Whereas the former persons may sometimes enter for very dubious reasons into history, responsible for killing people, the science of history draws on a whole lot of evidence, social, economic or demographic, to evaluate a person’s legacy or the merits of an epochal change. In the development of this scientific approach towards history, rather than a purely chronological, family structure or narrative-oriented approach, Marc Bloch has been a central figure. His research and exemplary own biography as student of history at the ENS in Paris, teacher and later Member of “La Résistance” is honored by an exhibition on his life and time at this formidable French institution of teacher training. In an exhibition in the ENS library you can even inspect a list of the books taken out by Marc Bloch as a student as well as his experiences as a student in London or Berlin before the 1st World War. A strictly science-based approach to history made him an influential historian and social scientist beyond his lifetime. (Image: Salle Marc Bloch at ENS Library Paris 2026-5)

Diamonds are forever

Due to the highly condensed carbon structure of diamonds, the use of diamonds has gone beyond the decorative stage. The difference between naturally grown or developed diamonds and the lab-produced diamonds has puzzled the market of the precious miniature materials. The paper by Zhang et al. 2026 has demonstrated that at the tiny size of a nano-structure the typically found hard structure of a diamond brakes down. The size-dependent softening of the diamond at the nano-size is a puzzle, but has been resolved with the explanation that on the surface the atoms remain rather stiff, only the inner structure of the cristalline core does “wobble”. Hence, diamonds are still almost forever, unless you crush them with far too much weight or power.

Light Locomotion

There are many politicians who have an innate tendency to move in the direction of any flash light or camera. Tenagers in the age of the “not-so-social media” have a similar reflex. More seriously, Science Advances, has presented a fully autonomous robot with such a behavior. In fact this form of light locomotion is named the “twirlbot”. It has been developed by Chi Chen et al. (2026) as a new kind of robot that can be directed using light impulses, as only energy source for moving towards the light source. The from of locomotion is inspired by nature (bionics) and more precisely the “tumbleweed” way of moving, better rolling forward, driven by wind energy. The tumbleweed-inspired rolling robot, short “twirlbot”, does not need mechanical devices, just energy in a specific frequency range of light, which provides the heat for the photoactive, otherwise passive, bilayer strips. The polyhedral geometry of the twirlbot allows omni-directional locomotion. It really resembles the light active politician or any posing in the spotlight while doing the “loco-motion” (Video Link performance by “Little Eva” in the early 60s or a late 80s version by Kylie Minogue).

Random randomness

In textbooks or courses of statistics, just as ordinary experiences with throwing a dice, we assume the perfect dice. This means the dice is assumed to have equal probabilities to roll on each side. Further, each throw of the dice of a sequence has an independent equal chance for each number to come up. To determine a “fair” dice we would throw the dice a thousand times to check, whether the probability of each side is about equal. However, the world of dices is not perfect and temporary or persistent margins of deviation are part of the real world. The weekly lotteries demonstrate this over and over again. Playing around with different shapes of dices makes the issue of probability tangible. Well worth to explore further empirically as well as a topic for inspiration of new approaches to learning about statistics. (Image: Dices produced by “devinsdice” Berlin 2026-5-5)
